Router or Firewall Suggestions for Multiple Public IP's

Hello Experts,
I tried to search for this info, but didn't come up with much... so I guess this might be a simple question for the network experts (I just hope that I am not posting something redundant).

Basically, I have done many installs using 1 public IP and route to an internet LAN using ports (NAT). However, I now have a situation where I need to use multiple public IP's (2-5) then route to different machines. A quick example would be to route port 80 on 2 different public IP's to 2 different internal machines.

I really don't know which router or firewall would do this. I am pretty sure that all the consumer level ones (like linksys or d-link) would only use 1 public IP.

1) could someone suggest model ranges that would do this? I am not looking to filter or block web contents, just for basic routing and translations, but using multple public static IP's. So I am hoping for models that are affordable and easy to manage.

2) this is just a bonus question.... more specifically, could a SonicWall Pro230 do this?

Anything you use if you have an ISP that is routing traffic or a block of IP addresses to you the device in from will have to answer for the publics do the translation for the backend units.

Any cisco router will do this and any decent firewall will do it as well. I would use a firewall because of control. A cisco 506E is a perfect fit for small to medium sized implimentations with no redundancy requirements.

hmmmm....
scott's quote "if you already need or have a router...":
security is not a concern, but I don't have a router already... just one of those SDSL modems from Covad (netopia)... so will the PIX do by itself or would I need to get a router as well or something with both combined?

Hi All,
Recently I have installed and configured a Sonicwall NS220 in the network as a firewall and Internet access gateway. All was working fine until users started reporting that they cannot use the Cisco VPN client to connect to the customer'…
